pers closed while they are u lifted. The A To all whom it may concern:

Be it known that 1, WILLIAM A. Bonn, a citizen of the United States, residing at Lynnfield, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the following description, in connection with the accom anying drawings, is a specification, like re erence characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines, and particularly to machines of the type shown in Letters Patent of the United States No. 584,744, dated June 15, 1897, andhas for one object to improve the construction and arrangement of the machine in various respects.

Another object of the invention is to pro-. vide means by which the operator may be relieved partially or entirely from the labor of holding the shoe against the thrust of the lasting devices and the impact of the tack driver.

With these objects in view one feature of the "ivention' consists in a novel construcment with a lower end face of the carrier,

'whereby rocking of said gripper jaw about its connection with the carrier is avoided when pressure is applied to its gripping face for holding and pulling stock. For further increasing the rigidity of the connection between the gripper jaw and its carrier the jaw is preferably I pinned or otherwise secured to the carrier at a plurality of points so that the jaw cannot pivot or turn in the carrier. In order to'obtain a firmer gripping of the stock by the two grippin jaws and prevent any tendency of the move le gripper jaw to turn laterally said movable jaw is connected to the fixed jaw b parallel links arranged at oppositesides o the jaws.

, In the type of machine in which the present invention is herein shown as emgrippers closing means is, t erefore, arranged to have a movement for closing the grippers and then to partake of the move ment of the uplifting mechanism. The ri pers closing means comprises a lever, wiic for the purpose of causing the rippers .to be maintained in their closed pos1tion while being uplifted, is mounted to move with one arm of a lever, herein called the updraw lever which forms one element of the mechanism for uplifting the grippers. Preferably the closing lever is actuated by a cam so located that movement of the closing lever with the updraw lever will not cause the grip on the stock to be relaxed. In accordance with a feature of the present invention the closing lever is arranged in alinement with its actuating cam and the grippers so that it applies force directly to the grippers. To facilitate this arrangement the updraw lever is bifurcated to allow the closing lever to be mounted centrally therein and, as shown, the updraw lever comprises parallel side bars fulcrumed upon trunnions carried by the machine frame.

As before mentioned, the machine comprises other lasting instrumentalities in addition to the grippers. These include a reciprocating presser which is actuated to press the upper pulled by the grippers over the last bottom and to hold it after the by the securing means. the presser should advance into holding engagement with the upper before the grippers release it and continue to hold the up- .per until the securing means has been applied. To meet different conditions it is desirable to vary the timing of the presser with relation to the movements of the other operating parts of the machine, and a feature of this invention consists in providing means by which the presser maybe advanced and retracted earlier or later in the cycle of the machines' operation. To this end an adjustable cam is provided which may be differently positionedto vary the time at which the presser is moved, but preferably without changing the position to which it is advanced. In the illustrated embodiment ofjthis invention another feature-is also included in that provision is made for varying the length-of time that the presser will be held in engagement with length required and a movable section which can be shifted to lengthen the cam face. As shown, the movable section can be positioned either to cause the presser to be advanced sooner or to keep it longer in holding engagement with the upper.

In lasting the toe portions of welt and turn shoes it is customary to anchor a wire to a tack at one side of the toe and superimpose the wire upon the successively overworked portions of u per as the lasting proceeds to the other slde of the toe, where the wire is anchored toanother tack. A wire thus placed binds the upper material against the lip or shoulder of the innersole or sole andholds it until it is permanently secured in place by the usual sewing operation. a

In accordance with another feature of this invention I have provided a novel construction and' arrangement of mechanism for supplying and presenting wire for this purpose inwhich the-wire is guided in an approximately straight course from the reel or spool through a tension device to a wire support, which islocated adjacent to the lastin devices and holds or presents the wire 1n position to be superimposed upon the successively overworked portions. of upper. Preferably the wire is guided centrally through the tension device so that an ap proximately uniform tension on the wire is maintained with any given adjustment of the tension device. This arrangement is of especial advantage when flat wire, or wire having one or more plane faces, is used for the reason that the wire while passing in an approximately straight course is not liable to twist in the tension device and present thereto sections of different thick? ness which would cause a non-uniform tensional resistance to be applied to the wire.

In'order to obtain slack for fastening the wire to an anchor tack and commence the lasting it is necessary to pull the wire through the tension device; but while -the lasting is inprogress it is desirable that thetension device should hold the wire with suflicient force to prevent the wire being.

for adjusting the tension device. As herein shown, the tension device comprises clamping plates yieldingly pressed together and provided with coiiperating cam surfaces and one of the plates is connected to a man- A feature of this invention consists in providing means by which the tension under which the wire is held when the machine is stopped may be readily varied. As herein shown,'means is provided for effecting an adjustment of the movable clamping plate with relation to the foot treadle or other means by which it is actuated.

As has been suggested, the wire is only employed while lasting the toe of the shoe, while tacks are employed for securing the upper at other portions of the shoe. The wire supporter before mentioned occupies an operative position substantially in the plane of the shoebottom and close to the lasting devices. While the shank, and sometimes other portions of the upper which are secured by tacks, is being lasted the wire supporter in this. position would be liable to interfere with the roper presentation of the shoe.. It is there ore desirable to move the supporter into a retracted position when ins not in use.

A further feature of this invention consists in novel means for moving the wire supporter toward and from its operative position. In the embodiment of the inven-: tionherein shown, the wire supporter is mounted eccentrically on a sliding carrier shaft which is arranged to be automatically rotated as it .is moved lengthwise, whereby the supporter is simultaneously retracted and turned upwardly away from the plane of the shoe bottom to place it where it will not interfere withthe operations of lasting the shank and other portions of the shoe. As herein shown, connected means is employed for moving the wire supporter toward and from its operative position and changing the tension applied by the tension device to the wire.

It issometimes desirable to employ the mechanism for actuating thegrippers laterally without also using the several parts of the wire presenting mechanism including the 'presser. As herein shown, the means for controlling the 'ppers-actuating mechanism is detachab y connected with the lneensfthrough whichi -the Presser, is ren dared o rative .or inoperative and the means 'it rou h which--. the. wire supportergives to the lever a longer throw than is required so that an -o erator has to raise 29 his foot unnecessarily igh to reengage the lever. To obviate this difliculty an adjustable stop is provided for limiting that movement of the lever which is effected by the spring in the direction to stop the machine.

Another feature of this invention consists in a shoe supporting jack mounted for sliding movement transversely of the machine and preferably connected with mechanism for actuating said jack to eifect and control the advance of the shoe for presenting sucessive portions thereof to the action of the lasting devices. This mechanism may also determine and control the position of the shoe during the operation of the lasting devices on it and relieve the operatorfrom the labor of supporting the shoe against the action of the lastin devices.

These and other eatures of the invention, including certain combinations of parts and details of construction, will. be explained more fully in the following description, and in connection with the accompanying drawings, and pointed out in the claims.

The machine which is shown as embodying the invention contains other novel features which will be described in connection with the complete machine but which are claimed in other applications about to be filed by me.

he frame of the machine-comprisesa post or standard 2 and a head 4, in the latter of which is supported a shaft 6, which vcarries a pulley 8 driven by a belt from a loose pulley 10 on a shaft 12, which is mounted in'the base of the machine. The shaft 12 also supports a driven pulley 14. The pulleys 10 and 14 are providedwithfriction disks 16 and 18 and the pulley 10 is actuated to bring its'disk 18 into contact with the disk 16 by=means of a treadle 20, which is connected to a wedge 22. The

wedge engages a sliding sleeve 24 that bears against the hub of pulley 10. .A spring25 connects the sleeve 24 with the frameand acts throu h a'hook standingin a groove in the hub'o the pulley 10 for separating the friction disks when pressure on the treadle is relieved. The wedge is provided with a stop screw 26 adapted to engage the frame and limit the upward movement of the treadle so that it shall notbe raised into a position higher than is convenient for the operator to reach.

The shaft 6 carries a cam block 30 having in its front face a cam groove 280, which acts through a connect-in plate E, a rod 32, and a spring 33 for li ting and depress- The lever apart and fulcrumed upon trunnions 35, 35, carried by the head of the machine. Said bars at the front end of the lever 34 are connected by a cross bar 36 which, with a block 38, forms a socket for a ball 39 on the upper end of the bar or shank 40 of the rigid member 42 of the grippers, which are best shown in Fig. 4. The cooperating movable gripper jaw 45 is operatively connected with the fixed member so that the grippers are depressed into gripping positlon and then uplifted to pull the stockby means of the lever 34, which is herein called the updraw lever.

The shank 40 is slotted from front to back at'its lower end and provided at the upper edge of the slot with an extended face 46. The fixed gripper jaw has a body portion shaped to fit in the slot in the shank and has an extended upper end face .47

adapted to fit against the end face 46 of the shank, This extended engagement between the upper end face of the gripper jaw and the face 46 of the shank'is designed to minimize the tendency of the gripper jaw to turn with relation to the shank when ressure is exerted against its gripping face or holding and pulling the stock. Forfui'ther insuring against the tendency of the gripper jaw to turn in its shank said parts are Connected at a plurality of points-by rivets or clamping bolts 48. This construction forms a very rigid connection between the gripper jaw and its shank and one which is not liable toiabecome loose under the rapidly recurring strains to which the grippers are subjected in the operation of the machine. The cooperating movable, gripper jaw is flexibly connected by a link 49 to its shank 50 and is connected to the rigid gripper jaw by parallel links 52 arranged at opposite sides of the gripper jaws, whereby they are spaced a considerable distance apart and prevent any swiveling of the movable jaw about a vertical axis.

The grippers are normally held open by a spring 60 which, rest-ing upon a collar 62 secured to the shank 40, presses upwardly against a pin 63 extending outwardly from the shank 50. The grippers are closed by depressing the shank 50 against the action of the spring 60 and "this movement is effected by a-lever 64 arranged in the central vertical plane of the machine between the side bars of the updraw lever 34. The closing lever 64 is fulcrumed at 65 on pivot studs carried by the updraw lever and extending transversely of said lever. The rear end of the closing lever carries an adjustable contact screw 67 which rests upon a block 69 that slides up and down in a vertical guide 691 which is located within the updraw lever and is formed in the portion of the frame in which the updraw lever is fulcrumed and from which rises the front one of the brackets 129 for the tack driver spring, later described. The block 69 bears a roll 66 which rests upon an edge cam 68 I carried by the shaft 6. This arrangement by which the block 69 has only a right line movement perpendicular to the axis of the cam allows the roll 66 to bear squarely upon the edge cam 68 at all times and avoids rapid wear of the cam, which would occur if the roll were carried directly on the closing lever and tilted with it. The cam .68 has an adjustable section 71 by which the time ja'cent to the fulcrum about which the levers 34 and 64 move together enables the closing .lever to move with the updraw lever about said fulcrum without being affected by the cam. By arranging the closing lever in alinement with its actuating cam the grippers force is transmitted directly from the lever without any tendency for the lever-to yielding element in the closing mechanism' allows the grippers to engage and hold with approximately the same force stock varying in thickness. In practice it is desirable that:

the movement of the closing lever be suflicient to cause. the spring surrounding the plunger to be compressed during each closing movement. The gripper shank 50 is provided with an adjustable stop 72 for engaging a stop; on the shank 40 of the rigid gripper and limiting the downward movement of the shank 50. By this arrangementthe movable gripper jaw may be prevented from contacting with the rigid gr pper jaw so that wear of their gripping faces, which are usually toothed or corrugated, may be prevented. This isdesirable because the machine is sometimes run without interposing stock between the gripper jaws and if said jaws were allowed to close against each other they would become worn and mutilated. The engagement of the gripper jaws when no stock is interposed also causes some noise which it is desirableto avoid. v

The machine is provided with pressers 75 and with means for reciprocating one of said pressers to force the pulled upper inwardly over the bottom of the last-into position to be secured. The pressers also assist in holding the upper in overworked position. during the interval between the opening of the grippers and the application of the fastening means. The actuating mechanism for the pressers comprises springs 76. which impel them rear-wardly and, a plunger 7 8 connected to a .lever fulcrumed at 82 at the rear of the machine and engaging at its upper end with a cam face on the rear side .of the cam block 30. Said cam block comprises a movable section 84, which is circu- 'larly adjustable on .the main portion, as

shown in Fig.- 5. The movable section of the cam block is formed as a ring or sleeve mounted in an annular recess in the rear end of the main section and carries a screw 85 which, in theadjustment of the movable section, travels in a slot 86 in the main section and may beset to secure the two sections in .desired relative positions. The movable section of the cam block is provided on its rear side with a cam siirface 88 for .actuatin'g the lever 80 to advance the presser. By adjusting the movable section ofthe cam block the time in the cycle of the machines operation at which the presser accuse advanced and retractedmayibe variedwith relation to the timing ofthe other moving parts of the-machine, as, forexamp'le, the grippers closing and uplifting means and the means for reciprocating the tack-'b1ock125 It is best that the presser be advanced into holding engagement with the upper before the grippers release the upper and as it is desirable, because of varying conditions which exist in different factoriesor in the manufacture of different shoes, to vary the time at which the grippers release the upper it is important to vary also the time at v which the jpresser advances.

The presser should always remain in holding engagement with'the upper until the securing means'has'been applied for holding the upper in overworked position. The time at which the presser may advanta eously release the upper varies under different con= ditins,for example, in the use of different securing means. To enable this variation in the timing of the presser to be effected, the main section of the cam block has acam surface 89 of the same height as the cam surface 88 on the movable section.

These twosectionsmay be placed in register when the ,presser is to be held in its advanced position for a minimum length of time, and the movable section may be shifted eitherforwardly or backwardly to cause the presser to advance earlier or to remain later in engagement with the upper.-

A rotary hopper 100 and an inclined raceway 102 form parts ofa mechanism for supaa. inclosed portion of the raceway. Those plying tacks to be driven forsecuring-the upper in overworked position. A portion of the raceway extends into the hopper and tacks are supplied in large numbers to this thereunder. At the inner side of this block an oscillating tack clearer 106' is arranged to sweep upwardly along the raceway for pushing back misplaced tacks and then, as it retreats, letting the tacks slide freely, under the block. The clearer is mounted movably in its holder and pressed yieldingly toward the raceway. The front face of the block 104 is concave, as shown in Fig. 2, and

' forms a guide for the clearer as it moves toward and from the raceway. The block fits snugly between the upper side of the raceway and the lower side of the raceway hole inthe hopper and is normally held reel for wire.

from slidin outof place by the removable cover- 110 w 'ich fits over the outer portion of the raceway. It frequently happens, however in the use of themachine that it is necessary to remove this cover in order to give'access to the raceway, and when this is done theblock 104 is liable to be forced out of position by the clearer. To insure against this occurrence a device 112 is provided for holding the block 104 against dis placement. This holding device is shown as aspring-pressed plunger mounted in a fixed portion of the hopper and having an operating handleengaging a cam face 105, which? is formed to retain the holder in an" elevated position when the holder is lifted and turned by the operating handle. The

holder is arranged to bear yieldingly upon the upper face of the block near its outer- I end and thereby serves another purpose in resisting the tendency of the clearers in their intermittent movement to rock the block andcause it to wear the relatively soft cast iron of the hopper which would allow the block 7 to become loose and unsatisfactory in use.

The main portion of the raceway is inclined, as shown, to cause tacks suspended by their heads on its up .er surface to slide down by gravity.

At t e delivery end of the raceway is arranged tack-separating mechanism comprising a reciprocatory blade 120 for se arating the lowermost tack in the raceway rom those above it. The upper faces 121 of the portion of the raceway upon which said lowermost tack is supported by its head are arranged at an angle to the head-supporting surfaces 122 of the main portion of the raceway so that the stem of the tack to be separated will hang at an angle or diverge from the stem of the. next tack above it and, therefore, provide a wider space for the passage of the separating blade than would be provided by tack stems hang-.

ing parallel to each other. Preferabl the faces 121 will extend horizontally, as s own in Fig. 6. After the separator blade passes between the tacks the separated tack forced by the slotted plate 124 mtoa position where it may fall into the. rec1procat-' ing tack carrier 125 from which it is inserted into the stock by a driver 126 actuated by a torsion-spring 128 held in brackets 129 that rise from the portion of the'frame in which the updraw lever 34 is fulcrumed. A

The machine is provided on its left-hand side with a bracket 130 on which is held a The wire extends from the reel through a tension device comprisin a bracket 132, having a fixed friction disk 134, cooperatin wlth a movable friction disk 136, see Figs. 8 and 9. 'The friction disks are pressed together by a spring 138 surrounding a post 140, the tension of the spring being controlled by a nut 142. From the tension device the wire passes overa ice 5 from the carrier so that its wire-guiding end I The carrier is being used which would be liable to twist in the tension device and cause unequal tension to be applied at different times if the wire were deflected from a straight course by the tension device. The post 140 is shown as provided with a transverse guide opening through which the wire passes and by which the WIIG is held centrally between the tension disks.

The wire supporter 145 is mounted in a carrier 146, being bent or deflected laterally is eccentric to the carrier. mounted for movement in the machine frame and provided near its rear end with a block 148 having an inclined groove 150,

as indicated in dotted lines in Fig. 8. The

groove 150 receives a stud 152 ona sliding bar 154 connected with one arm 153 of a rock'shaft 155, the other arm of which is formed as a knee lever 156, see Fig. 3. The carrier 146 is provided with a spiral groove 160 in which stands a stud162. With this arrangement the wire guide may be moved toward and from its operativeposition by the knee lever 156 and in retreating from its operative position it will not only be moved backwardly, but will be turned to carry its wire-guiding. end upwardly out of the plane in which is located the bottom of the shoe being lasted. With this arrangemen't the wire supporter is caused to assume the inoperative position shown in Fig. 1 where it is not liable to interfere with the proper presentation of any part of a shoe to the lasting devices.

The friction disksl34, 136 of the tension device are provided with cam surfaces, as shown in Fig. 9, which are so formed that when they are in register, as shown therein, the disks may be pressed by the spring 138 as close together, as the wire will permit and the wire will, therefore, be held with the full force of the tension spring. The disk 136 has a radially extending arm 170 by which it may be turned to'cause its cam face to ride up onthe cam face of the disk 134: and diminish the tension on the wire.

This is desirable at times in order to enable the wire to be drawn more easily through the tension device. The arm 170 is connected by a rod 172 with a bell crank lever 174 and the bell crank is connected by rods 175 and 176, see Fig. 7, with the foot treadle 20 so that by depressing the treadle the friction disk 136 may be turned. A spring 178 act ing on the rod 176 moves the treadle and the connected parts in the reverse direction. As the treadle 20 is alsoemployed for starting the machine the parts of the tension device are so arran ed that when the treadle is depressed the frictionplate 136 is moved to put its cam face inregister with the cam face on the disk 134 and the wire is clamped. \Vhen the treadle is released the s ring 178 reversely moves the parts and iminishes the tension on the wire. The extent to which the disk 136 is moved for this. purpose and therefore the degree of tension under which the wire is held when the treadle is released may be determined by the adjustment of a turn buckle 180, shown as movably connecting two arts of the rod 175 Another arrangement or varying the ten sion with which the wire is held is illus trated in Fig. 11 wherein the rotatable tension disk 136 is provided with an arm 171, which, by means of an adjustable finger 173 and stops 183 and 187, is arranged to be actuated by the carrier 146 upon which the wire supporter is mounted. This carrier, it

will be remembered, is moved lengthwise by manipulation of the knee lever 156. This construction enables,v the tension on the wire to be varied independently of the starting and stopping of the machine. As herein shown the knee lever and its connected rockshaft 155 may be employed for connecting and disconnecting the presser 75 from its actuating. mechanism. To' this end' the shaft has an arm 193, to which is connected a slide. 195, havinga guideway 197, in which the plunger 78 reciprocates and by which the head'of the plunger is held ,in position to engage a cooperating shoulder on the presser 75, as shown in Fig. 8, when the presser is to be actuated. When the presser is not to be actuated the knee lever will be moved to turn the shaft 155 in the direction to shift the slide 195 to the right in Fig. 8 and the'slide will withdraw the head of theplunger from position to engage and actuate the presser. The same movement which disconnects the plunger 78 from the presser will retract the carrier 146 to move the wire supporter into its inoperative position and will, in accordance with the construction-shownin Fig. 11, manipulate the tension device to relax the tension on the 'wire. The extent to which the tension on the wire will be relaxed may be varied by adjusting the finger 173 upon the arm 171,

this adjustment being effected by the pinand-slot connection 177, 179.

1 The-cam block which has the cam surface 68 heretofore mentioned has also a' cam groove 260 through which a lever 262 is ac- 266, having on its end a segment block 268 which is rocked with each revoluti of the cam. A slide 270 is mounted in the inner face of the segment block and is connected 5 by a link 272 with the grippers as shown in Fig. 12, and more fully explained in the prior patent before mentioned. The rockshaft 155 has at its upper endan arm 275 that engages a loose sliding collar 276 on the sleeve shaft. The collar has a stud 27 8 that extends throughQi spiral slot in the sleeve shaft 266 and into a shaft 280, see Fig. 3, so that when the collar is moved lengthwise ofthe shafts by the rockshaft 155 the inner shaft 280 will be turned. This inner shaft .has on its front end a pinion 282 best shown in Fig. 1, by which the slide 270 is adjusted toward and from .the center about which the sleeve shaft is oscillated by the lever 262. When the slide is eccentric to said sleeve shaft motion will be transmitted from the segment block 268 through the link272 to move the grippers laterally to plait the up- 4 per. When however the slide is adjusted by the rockshaft 155 and the described connections into alinement with the axis of the sleeve shaft no motion will be transmitted from the segment block to the grippers. The rockshaft 155 thus constitutes controlling means for rendering operative or in operative the mechanism for moving the grippers laterally. A second link 285 connects the slide 270 with a lever 286 which is joined by a link 288 with a rack bar 290 that shank 40, see Fig. 4. By this connection the grippers are turned as well as moved laterally when the described actuating mechanism is operatively connected with them. To enable the rockshaft to be employed for controlling the grippers actuating mechanism without adjustin the presser actuating plunger 78, the wire supporter 145, or the tension device if the construction shown in Fig. 11 be employed, the arms 153 and 193 may be detachably connected -to the rockshaft as shown in Fig. 3. The connection'. comprises a collar 292 pinned to the rockshaft and carrying a spring pressed plunger 294 that can enter a seat in the lower side of the hub on which the arms 153 and 193 are formed. The plunger is pro vided with a handle 295 that rests on an incline 291 up which it may be forced to with draw the plunger and disconnect the rockshaft from said arms and the parts connected with the arms. A seat 299 in the collar 292 receives the handle and retains the plunger in its retracted position. A spring plunger 193, see Fig. 11, may be employed to hold the several parts connected with the rockshaft in their adjusted position, and when the arms 1153 and 193 are disconnected from the rockshaft the plun-' ger will hold the parts controlled by said engages teeth on the head 39 of the gripper arms in whatever position they may bead-- justed, as, for example, in. the operative" toe rest 200 and a heel pin 202. The'toe rest is mounted in a carriage which is adjustahle longitudinally of the shoe. upon a plate204 and held in adjusted position'bya binding screw 205. The heel pin is mounted ona lever 206, which is pivoted on the carriage 208, also adjustable longitudinally of the shoe u on the plate 204. The lever 206'is presse in the direction to rock the shoe downwardly against the toe rest by means of a spring 210 The plate 204-is pivotally connected at 212 to a block 214, having a segment-shaped lower face guided in a post 215. The post and jack are yieldingly sustained in a spindle '216 by a spring 218 and the spindle is pivotally connected at 220 to a slide 222. The slide 222 is arranged for movement transversely of the machine in a bracket 225 secured to the standard 2. The slide 222 is slotted at 226 to permit the point of supportfor the post tobe adjusted toward and from the machine and said slide is provided-with an adjustable stop 228 to limit the tipping movement of the jack away from the machine. With this construction it will be evident that the shoe is mechanically upheld to .the action of the lasting and tack-driving devices, thus relieving the operator from the labor involved in holding the shoe in proper position to receive to the best advantage the action of.

the lasting devices.

' Means is also provided which ma be employed at the will of the operator or feeding the shoe supported on the jack in a direction' transversely of the machine. The slide 222 is provided on its lower face with rack teeth engaged by a pinion 230 on a shaft 232 loosely mounted in the bracket 225. The shaft 232 carries a clutch member 2334 adapted to be engaged by a sliding clutch member 236 fast on a shaft 238. The latter shaft also carries a ratchet wheel 240, as shown in Fig. 10, the ratchet being engaged by a pawl 242 on a pawl carrier 244, which is actuated by a link and lever connection 245with a cam track 246 in a cam disk mounted on the main shaft 6.

mechanism thus arranged moves the jack and the shoe thereon from left to right, which is the direction in which it is customary to progress with the'lastingof a shoe. A clutch-operating lever 250 is provided for disconnectlng the clutch members 234 and The lever extends into The side of the shoe and progresses toward the toe it is usually desirable to stop the feeding of the shoe while rounding the toe, as it is only necessary at this time to turn the shoe without advancing it materially. The feeding of the shoe can be stopped by operating the lever 250 when the toe is reached and the feeding resumed by reversing the lever when the toe has been rounded. The slide 222 is provided with an inclined face 260 adapted to be engaged by an arm of the lever 250 and actuate said lever to disconnect the clutch members and stop the feeding of the shoe when the slide reaches the end of its. ossible movement. When the clutch mem ers are disconnected the slide may be moved freely in either direction and a crank 265 is shown as provided to turn the shaft 232 for this purpose.

The tack block heretofore referred to and designated as a whole by the reference character 125 in 3 is mounted on a forwardly and backwardly moving slide actuated by a lever and cam connection with the driving shaft 6, substantially as in said prior patent. The tack block is advanced over the shoe bottom into position for a tack therein to be driven for securing the upper after the upper has been pulled by the grippers. The tack block may be constructed as shown in detail in Figs. 13 and 14, wherein. the carrier 180 has a tack and driver passage 182 in which a tack may be supported by the fingers 184, pivoted at 185 in the fore part of a longitudinal groove 188 in the carrier. The fingers are arranged one in advance of the other, as shown, to allow the tack block to be made narrow. This is particularly desirable in machines used for lasting the heel seats of turn shoes, for in this work it is necessary that the tack block advance under the upturned heel end of the sole and drive tacks as close as .possible to the angle between the sole and upper. The fingers 18 1 are yieldingly held pressed together to support thetack, but

allowthe driver to force the tack therebetween by means which includes a loop 186 seated in a groove in the front finger and extending rearwardly with its side arms embracing the sides of the fingers. The rear ends-of the side arms are inturned to form hooks that extend through the walls of a spring case and terminate between two collars on a plunger 192. The plunger is engaged by a spring 190 seated in the case and the front end of the plunger rests in a recess in the back side of the rear finger 184. With this arrangement the one spring 190 acting in one direction through the loop 186 and in the .reverse direction through the plunger 192 holds the two fingers yieldingly toward each other with equal force. The ends of the loop stand in the space 194 between the casing and the reduced portion 192 of the plunger and by limiting. the forward movement of the plunger centert-he two tack fingers with relation to the driver passage 182. In the use of the machine the shoe is presented either upon the jack or in the hands of the workman in position for the upper to be engaged by the grippers, which pull it over the bottom of the last, after which the pressers intheir operation force it into position to be secured and the reciprocating tack block advances into position for a tack to be driven. The heel and sides of the shoe are usually fastened by tacks and when the toe of the shoe is reached the foot treadle is usually released and the machine stopped. The wire is then pulled through the tension device, the clamping disks of which will at that time have been separated sufiiciently to allow the wire to be pulled through easily. The end of the wire is anchored to the last driven tack and when the machine is restarted the lasting proceeds around the toe of the shoe. The wire which is held taut by the tension device is pulled from the reel as the lasting progresses, and is superimposed. in position to hold the overworked upper. When the lasting has been completed around the toe of the shoe the machine is again stopped andthe wire anchored to a tack driven on that side of the shoe. If the shoe-feeding means is employed it will advance the shoe step-by-step' as the lasting proceeds along the side and when the toe is reached the feedin means may be stop ed by manipulating t e lever 250, until t e other side of the shoe is reached, when the feeding means will be again-started. While lasting the heel of the shoe it is the custom of many operators to hold the shoe so that the grippers do not engage the shoe and the upper is wiped into lasted position by the tack block. The stops on the shanks of the gripper bars prevent the grippers being closed to wear the gripping faces on the jaws at such times when no stock is interposed between'said faces.
